Abstract
Official abstract text for this publication.
A method and apparatus provide antenna array channel feedback. The method can include receiving, at a wireless terminal, a set of channel state information reference signals. The method can include determining a precoding matrix based on the received set of channel state information reference signals. The precoding matrix can have a representation in terms of three components. The first component of the three components can be determined from a first set of vectors. The second component of the three components can be determined from a first set of parameters. The third component of the three components can be determined from a second set of parameters. The second set of parameters can be a set of unit-magnitude scalars. The method can include transmitting, by the wireless terminal, a representation of at least one of the first component, the second component, and the third component.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: receiving, at a wireless terminal, a set of channel state information reference signals; determining, by the wireless terminal, a precoding matrix based on the received set of channel state information reference signals, where the precoding matrix has a representation in terms of three components, where the first component of the three components is determined from a first set of vectors, where the first set of vectors are determined by a firs…
